Oh, I just saw that Perl is "violating POSIX" since Perl 1:
close-on-exec flag in set on new created file descriptors if their
number is greater than $SYSTEM_FD_MAX (which is usually 2).

So Python would not be the only language providing a convinient
default behaviour ;-) (And Ruby 2 will also set close-on-exec by
default.)
